This paper demonstrates that a pollution tax with a fixed cost component may lead, by itself, to segregation between clean and dirty firms without heterogeneous preferences or increasing returns. We construct a simple model with two locations and two industries (clean and dirty) where pollution...

The long-term trends of urbanization suggest: not only have more cities formed, but the leading metropolises have grown larger, with a number of peripheral subcenters developing over time. Conventional models of urban growth are limited, in that commuting cost and congestion eventually result in...

What are the effects of the WTO’s TRIPS Agreement on growth, welfare and income inequality? To analyze this question, we develop an open-economy R&D-growth model with wealth heterogeneity. Under TRIPS, the North experiences higher growth and welfare at the expense of higher income inequality....

What are the effects of strengthening developing countries' protection for intellectual property rights on economic growth, social welfare and income inequality in the global economy? To analyze this question, we develop a two-country R&D-based growth model with wealth heterogeneity. We find...

What are the effects of the WTO's TRIPS Agreement on growth, welfare and income inequality? To analyze this question, we develop an open-economy R&D-driven endogenous-growth model with wealth heterogeneity. Under TRIPS, the North experiences higher growth and welfare at the expense of higher...

Knowledge creation either in isolation or joint with another person, using either face to face or internet contact and incorporating internet search ability is analyzed. Both a conceptual phase and a technical phase of research are analyzed, allowing workers to choose endogenously their mode of...

This paper begins with a survey of the literature on the political economy approaches to labor income taxation. We focus on recent progress made by examining in detail the specific properties of non-linear taxes derived in the context of voting. Next, we present new results on the existence of...

The literatures dealing with voting, optimal income taxation, implementation, and pure public goods are drawn on here to address the problem of voting over income taxes to finance a public good. In contrast with previous articles, general nonlinear income taxes that affect the labor-leisure...
